Are Xcode 4 and iOS SDK 4.3 compatible with Snow Leopard?

Question

Currently I am using Xcode 3 and iOS SDK 4.2 on Snow Leopard. I am planning to download and install Xcode 4 and iOS SDK 4.3.

I would like to know if Xcode 4 and iOS SDK 4.3 are compatible with Snow Leopard.

Answer 1

Yes..You will have separate .dmg available for download when you visit iOS developer center X-Code download link.

Please do note that the X-Code 4.2 will have iOS 5 simulator and library only. If you want lower version simulator and library with X-Code just goto X.Code->Prefrences-> Downloads Tab. In downloads tab you'll have two tabs:

1) Components - Here you will have option to download iOS 4.3 simulator(~600 Mb), iOS 4.0-4.1(~670 MB) Device debugging support, iOS 3.0-3.2.2(686.3 MB) Device debugging support.

2) Documentation- Yoy will have option to download iOS 5.0,XCode 4.2 Developer libaray,Mac OSX 10.7 Core Library.

Install the components which ever you need and there you go..

Hope that helps.

Answer 2

There's a specific version of Xcode 4.2 (and likely earlier versions) that can be used on Snow Leopard. That's the version I use on my iMac. Note that you can use 4.2 w/iOS5 SDK and still deploy on older devices (and even download the 4.3 simulator) in case you cannot find Xcode 4.

However you cannot use (download) the one from the AppStore which is Lion-specific. To find the Snow Leopard specific version log into Apple's developers portal and you'll see separate links for SL and Lion.
